I'm surprised this works. Shouldn't virtual methods you expect to override be in
the protected section in the parent class?

[Roger Tawa OOO till Jul 10th, 2013/01/24 23:30:10]

No.  This is common to allow behaviour to be overridden by derived classes while
not increasing the visible api of the class.

I've seen this in subclasses, but never in the parent.
